跨域的解决办法

单个控制器方法CORS注解 

@RestController
@RequestMapping("/system/test")
public class TestController {

    @CrossOrigin
    @GetMapping("/{id}")
    public AjaxResult getUser(@PathVariable Integer userId) {
        // ...
    }
	
	@DeleteMapping("/{userId}")
    public AjaxResult delete(@PathVariable Integer userId) {
        // ...
    }
}

整个控制器启用CORS注解

@CrossOrigin(origins = "http://ruoyi.vip", maxAge = 3600)
@RestController
@RequestMapping("/system/test")
public class TestController {

    @GetMapping("/{id}")
    public AjaxResult getUser(@PathVariable Integer userId) {
        // ...
    }
	
	@DeleteMapping("/{userId}")
    public AjaxResult delete(@PathVariable Integer userId) {
        // ...
    }
}

 全局cors

/**
 * web跨域访问配置
 */
@Override
public void addCorsMappings(CorsRegistry registry)
{
	// 设置允许跨域的路径
	registry.addMapping("/**")
			// 设置允许跨域请求的域名
			.allowedOrigins("*")
			// 是否允许证书
			.allowCredentials(true)
			// 设置允许的方法
			.allowedMethods("GET", "POST", "DELETE", "PUT")
			// 设置允许的header属性
			.allowedHeaders("*")
			// 跨域允许时间
			.maxAge(3600);
}

CorsFilter 

 
@Configuration
public class CorsConfig {

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addExposedHeader("token");
        corsConfiguration.addAllowedMethod("*");

        corsConfiguration.setMaxAge(3600L);         // 预检请求的有效期，单位为秒。
        corsConfiguration.setAllowCredentials(true);// 是否支持安全证书(必需参数)

        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }

}

filter

public class EncryptFilter implements Filter {
 

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
                         FilterChain chain) throws IOException, ServletException {
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        httpResponse.addHeader("Access-Control-Allow-Origin", "*");
        httpResponse.addHeader("Access-Control-Allow-Headers","X-Requested-With");
        httpResponse.addHeader("Access-Control-Allow-Headers","content-type");
        httpResponse.addHeader("Access-Control-Allow-Headers","cert");
        httpResponse.addHeader("Access-Control-Allow-Headers","t");
        httpResponse.addHeader("Access-Control-Allow-Headers","content-length");
     
        chain.doFilter(request, response);
    }

}
